SLIDING WINDOW-BLIND.

SPECIFICATION forming part of Letters Patent No. 364,955, dated June 14,1887.

Application filed March Q2, 1886.

To all whom t may concern:

Be it known that I, GEORGE PorrER'r, of Milwaukee, in the county ofMilwaukee, and in the State of Visconsin, have invented certain new anduseful Improvements in Sliding Vindow-Blinds; and I do hereby declarethat the following is a full, clear, and exact description thereof.

My invention relates to sliding windowblinds; and it consists iu certainpeculiarities of construction, as will be fully set forth hereinafter.

In the drawings, Figure l isa vertical crosssection of my presentdevice. Fig. 2isahorizontal section on the line z z or Fig. l. Fig. 3 isa section on thelineof Fig. 4, and Fig. 4. is a section on the line y yof Fig. 3. Figs. 5 and 6 are details of other forms of my invention.

A represents one of the jambs or side pieces of the wiudowcasing, and AA' the window sashes.

B B B2 are the sliding window-blinds, three such being shown in thepresent case, but the number being immaterial.

C are the guide-strips,having beads c c c on vthe outer surfacecorresponding in number to the number of blinds in any given case, andthe edges of the stiles of the sliding blinds are :furrowed out to formcoves b, corresponding in shape to the said beads,upon which they slide.The strips C have partitions c formed therewith on the side opposite tothe beads, and extending backward against the jambs A to form spaces cto receive the weights D, which are attached by cords, chains, or cablesd to the sliding blinds. rIhe said cords pass over pulleys E, secured tothe upper part of the guide-strips O, and are secured to the upperportions of the blinds,which arc hollowed out, as shown at b in Fig. 3,for this purpose.

The weights D and the blinds B B', 85e., just counterbalance each other,and hence the blinds will remain in any desired position to which theymay be moved. It will be understood that the guidestrips and weights,&c., are designed to be employed at each side of the window-casing. Theguide-strips are independent from the jambs, and are attached thereto inany suitable manner, as by screws a', as shown in Fig. 2.

Serial No. 196.120. (No model.)

The pulleys E are all preferably mounted on a plate or plates, e,secured to the upper part of the guide-strips C, which are cut out fortheir reception, as shown.

Under some circumstances it-may be desirable (as when the window isnarrow) to utilize the jambs A for the formation of the compartments a.This may be done in a variety of ways, two of which I have shown inFigs. 5 and 6. In Fig. 5 the janib A is cut out to first form one widegroove, and the end or outside partitions, c', of the guide-strips C aredispensed with and the strips C then applied, as shown, thereby formingthe desired compartments or spaces et for the weights D.

In Fig. 6 the jamb is shown with a series of grooves, and the partitionsc form part of the jambs A instead of part of the strips C, and in thisform the strips G are smooth upon one surface, though in both instancesjust described they have t-he beads c c c upon their other surfaces.

My devices may be variously modified in other ways without departingfrom the spirit of my invention, so long as a consecutive series ofcompartments, a a, are provided for the weights D between the jainbs andguidestrips.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination of the casing of a window with the guide-strip O, havingpartitions c', forming compartments a between them on one side and beadsc on the other side, said beads being cutaway at the top. pulleysE,secured to the strips at said upper eut-away portions, sliding blindsB B', &e., having grooves b formed in the edges of their stiles and cutaway or hollowed out, as at b, in their upper edges, and the weights D,and cords, chains, or cables d, secured to said weights and to saidblinds at the point b and passing over the pulleys E, substantially asset forth.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Visconsin, in thepresence of two witnesses.

GEORGE POPPEET.
